A block slides on a frictionless table to the right, which is defined as the positive x-direction. At time t = 0, the object is at x₀ = 4 m and is moving with a velocity v₀ = 6 m/s. A force pushes the subject to the right, as shown in the figure. The force is not constant. It changes with time in such a way that the power delivered to the object is constant (always the same). At the t = 0, the force has a magnitude of 5 N. What is the power delivered to the block in Watts and is the block's acceleration increasing, decreasing, or constant?
